Have strep throat, loss of appetite, fever and pain. On Ibuprofen. Should I discontinue course?

I have strep throat - experiencing loss of appetite- even before antibiotics- thinking might be associated with the ibuprofren I have been taking for the pain and fever. Have been taking the 400mg every 4 to 6 hours max 8 pills a day. Will my appetite return once I stop taking it, or is this a more serious side effect ?
